Comet impact theory replaced by common house fires
The uncertainty of science: Fused droplets found in many places across the globe and theorized to have come from a comet major impact that caused a major climate change around 13,000 years ago have now been found to have instead come from common house fires.
Since the 1970s when the Walter Alvarez found evidence of an asteroid impact in the Yucatan that could have caused the dinosaur extinction 65 million years ago, planetary scientists have seen asteroid or comet impacts everywhere. After all, impacts are cool disasters that play well to television producers and funding agencies.
Read this story however. It describes some very solid scientific work that wipes out one one of those cool theories, replacing it with something quite mundane.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
